Is It Any Good?

This digital cash site is an interesting concept, but its complexity is better left to tech-savvy users. Because it involves a blockchain structure, CryptoKitties could, in theory, offer kids a chance to see the emerging technology in practice. It could also offer dynamic budgeting experience, or a deeper understanding of the way genetics work. To do that, though, the site would need more educationally based content; aside from a few brief FAQ descriptions, there really isn't any material that delves deep into what blockchain technology involves or the ins and outs of how genetic material is passed from generation to generation. In addition, CryptoKitties' pay-to-play aspect is a pretty big detriment. Until you put some money into a digital wallet, you can't really do much on the site, aside from looking at cats that are available for sale and for breeding. In its early days, the site apparently gave out some free kitties; today, to get started, users need a MetaMask digital wallet and some Ether, a form of digital payment. They'll also need a computer or laptop that can run the desktop version of Chrome or Firefox, the only two browsers CryptoKitties works on. Kids could potentially get a chance while playing to make budgeting decisions, but given that they have to exchange real money for digital currency to breed or buy kitties, that's not a scenario all parents may be comfortable with.

Did we miss something on diversity?

Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.
